After last year's Ryan Seacrest-in-the-round extravaganza, today comes more exciting news about a significant shakeup in the Emmy Awards format: This year's ceremony, scheduled for September 21 at the roomy Nokia Theatre, will be presided over by the five nominees in the new category of best reality host. (The shape of the stage is still under wraps, but we hear ABC is toying with an M.C. Escher-inspired endless staircase design that will provide raked seating for days!) Seacrest, nominated for his hosting duties on American Idol, will be joined by Survivor's Jeff Probst, Dancing with the Stars's Tom Bergeron, Deal or No Deal's Howie Mandel, and Project Runway's Heidi Klum. We've run promotional photos of all five hosts through our Defamer Combine-O-Tron 2000 (patent pending; any similarities to Late Night's If They Mated completely coincidental) to see what the host would look like if they melded them into one. The result? A not-particuarly-telegenic überhost, and distant cousin of the rare and wonderful pigkey! [Photos: LAT]
